Code of Practice for the Discharge of Produced Water from Coalbed Gas Operations
The Ministry of Environment has amended the Environmental Management Act (EMA) Coalbed Gas Code of Practice to reflect the commitment made in the "The BC Energy Plan: A Vision for Clean Energy Leadership". The amendment to the Coalbed Gas Code of Practice prohibits the surface discharge of produced water from coalbed gas operations unless an exemption has been granted under the Waste Discharge Regulation. Produced water must be disposed of to an underground formation in accordance with the Oil and Gas Waste Regulation.

Background Information
What is Coalbed Gas?
British Columbia is home to a wealth of natural resources, among them natural gas. Coalbed gas (CBG) is natural gas found in underground coal deposits.
How is CBG extracted?
This gas is contained within the coal seam where it is adsorbed or attached to the coal particles. Pressure from the overlying rock and the water within the coal seam keeps the methane adsorbed in the coal. During production, water is pumped out of the coal seams, lowering the pressure and thus releasing the gas to be collected and sent to market.
